PERU S. IBRKICH, OF ST. LOUIS, MISSOURI, ASSIGNOR OF ONE-HALF 'IO GEORGE SEPER, OF ST. LOUIS, MISSOURI.

TIE.

Application filed July 17, 1924. Serial No. 726,420.

To all whom it may concern.

Be itknown that I, Pnno S. BRKICH, a citizen of the Republic of Yugoslavia, residing at St. Louis, State of Missouri, have 5 invented certain new and useful Improvements in Ties, of which the following is a specification.

The object of my device is to make a tie that is made of an integral, metallic shell filled with a mixture of concrete and straw. A further object is to devise a tie which is made of few and simple parts that lend themselves readily to multiple production and that can be easily handled and repaired. A further object is to make a tie that will not crack in its center under the ordinary stresses of practical use. With these and other objects in view, my invention has relation to certain novel features of construction and arrangement of parts as will be hereinafter more fully described, pointed out in the claims, and illustrated in the drawings, in which Fig. 1 is a perspective view of the shell of my tie.

Fig. 2 is a front elevation of my complete tie, showing the concrete and straw in position.

Fig. 3 is a cross section on the line 33 of Fig. 2.

Fig. 4 is across section on the line 4-4t of Fig. 2.

Fig. 5 is a cross section on the line 55 of Fig. 2.

Numeral 6 designates the shell generally preferably made of metal and open at the lateral sides. The inside of the shell is filled with a mixture 7 of concrete and straw. An elevation 8 is formed in the bottom 01": the shell. Slots 9 are formed in the top of the shell 6 for the reception of rails. There are two such slots in each tie and they are spaced apart such a distance that when the rails are slipped into them, the rails will be 4 in the standard spaced relationship. It will be seen that the elevation S is formed by bringing the wall of the shell in contact with the upper wall of the shell and that there is no space or concrete left between the upper and lower walls of the shell at this point. The

reason that no concrete is positioned at this point is because metal is more resilient than concrete. When the tie is subjected to an uneven pressure on the rails so that one end is bent relative the other, the concrete would crack, whereas the metal, being resilient, will not crack but will bend. lieved the metal,

lVhen the pressure is reowing to its resilience will assume its original form and position.

In filling the tie with concrete, 1t is laid on one ofits open sides on a board or other suitable surface,

and the concrete mixture is poured in until the mixture is flush with the top wall of the shell.

This position is maintained until the cement sets. Any of the conventional mixtures of sand, gravel, etc, and aggregate may be used. The straw prevents the concrete from cracking when in use and holds the mass together. The shell is usually cast in one piece but may be stamped welded together.

out and bent and the ends lVhat I claim and mean to secure by Letters Patent is,

straw.

3. A tie comprising a shell having an elevation formed in one of its sides, which ole vation extends to the opposite wall 01 the shell, said shell having rail slots formed on one of its sides.

In testimony whereof I ailix my signature.
